Continental 4 Seasons Grand Prix gear reviews

These 4 Season tires have 'Duraskin', a polyamide layer to supposedly resist punctures and abrasion. I would rather sacrifice some tire weight for a more durable, flat resistance tire-cause I am slow anyway and have no immediate AG rank aspirations.

I have just changed to Bontrager Race Lite Hard Case with a Kevlar layer to hopefully reduce the frequency of flats on recommendation by the LBS. I was interested in the Continental Gatorskins but couldn't find any locally.
